Class evidence is useful in an investigation because it helps link evidence to a broader group of items rather than identifying an individual uniquely. This type of evidence serves to establish connections between various pieces of evidence, which can be essential in building a case. For example, if a certain type of tire tread is found at a crime scene, it can be linked to a particular make and model of vehicles, suggesting that multiple vehicles could have been present. This broadening of the scope allows investigators to explore multiple leads and correlations related to the case.

While class evidence may not offer the individual specificity needed to pinpoint a single suspect or guarantee a conviction, it can significantly contribute to the overall investigation by placing potential suspects in the vicinity or connecting them to the crime through shared characteristics. This aspect of class evidence underlines its importance in forensic science, as it helps build a context for the investigation even when it does not provide definitive proof.
